Abstract:Extragalactic planetary nebulae (PNe) offer a way to determine the distance to their host galaxies thanks to the nearly universal shape of the luminosity function (PNLF). Accurate PNe distance measurements rely on obtaining well- sampled PNLFs and the number of observed PNe scales with the encompassed stellar mass. This means either disposing of wide-field observations or on focusing on the bright central regions of galaxies. In this work we take this second approach and conduct a census of the PNe population in the central regions of galaxies in the Fornax cluster, using VLT/MUSE data for the early- type galaxies observed over the course of the Fornax3D survey. Using such integral-field spectroscopic observations to carefully separate
